// Catching errors by type
try {
  await lakebase.query("...");
} catch (e) {
  if (e instanceof AuthenticationError) {
    // Re-authenticate
  } else if (e instanceof ConnectionError && e.isRetryable) {
    // Retry with backoff
  }
}

// Logging errors
console.error(error.toJSON()); // Safe for logging, sensitive values redacted
